'My invention relates to carcass splitting machines and more particularly to machines operated bycompressed air; and the object is I to provide machines for splitting carcasses in practical andeconomical manner and to provide machines in which the saw is ar-' ranged or off-setrelativeto the motor so' that the operator can see the operation of a saw directly without'obstruc'tion thereby ob-- taining better vision andcontrol and a balancing of the machine.

All moving, parts are completely inclosed and running in oil bath [and no damage can result from water, blood'o'r dust as the Inachine is sealed against such elements.

The necessary sanitary condltions on killing floors are easily met since a dip in hot water cleanses the machine perfectly and will not damage the machine. The machine may also be cleansed with a hose. 7

No cross-head for the saw is used. A Scotchyoke is used and its arm extends out of the casing through a packing boxand the going each way and has large deep pockets between the teeth to bring out the dust to prevent clogging.

and

The saw is supported entirely by an arm ofthe Scotch yoke which extends out of the housing through a stuffing box and has no rear end support other than the Scotch" oke.

The front end is slotted and runs on a har ened roller to lessen friction, and consequentlylesisi power is required-and unsanitary pockets i vertlcally.v

for meat and blood are eliminated.

' New sharp blades'are often needed and the change can be quickly made because ofrthe simplicity of the saw connection and support.

The saw is'cleaned with an air blast often after the cutting of each carcass or can be set so that it clearsv and blows dust and blood and flesh downwardly all the time the saw is running, thus aiding in sanitation and cleaner operation; In hot climates this work is fect finish.
